2009-07-02Move the v3 resource allocator to v2.Myles Watson
Major changes: 1. Separate resource allocation into: A. Read Resources B. Avoid fixed resources (constrain limits) C. Allocate resources D. Set resources Usage notes: Resources which have IORESOURCE_FIXED set in the flags constrain the placement of other resources. All fixed resources will end up outside (above or below) the allocated resources. Domains usually start with base = 0 and limit = 2^address_bits - 1. I've added an IOAPIC to all platforms so that the old limit of 0xfec00000 is still there for resources. Some platforms may want to change that, but I didn't want to break anyone's board. Resources are allocated in a single block for memory and another for I/O. Currently the resource allocator doesn't support holes. Signed-off-by: Myles Watson <mylesgw@gmail.com> Acked-by: Ronald G.

2007-04-22Add explicit license headers to all files in src/device.Uwe Hermann
For files derived from the Linux kernel we merely add a small header which states the origin of the file and the copyright owners of the modifications to the file. We know all files from Linux are licensed under the GPLv2.

2004-10-30- To reduce confuse rename the parts of linuxbios bios that run fromEric Biederman
ram linuxbios_ram instead of linuxbios_c and linuxbios_payload... - Reordered the linker sections so the LinuxBIOS fallback image can take more the 64KiB on x86 - ROM_IMAGE_SIZE now will work when it is specified as larger than 64KiB. - Tweaked the reset16.inc and reset16.lds to move the sanity check to see if everything will work. - Start using romcc's built in preprocessor (This will simplify header compiler checks) - Add helper functions for examining all of the resources - Remove debug strings from chip.h - Add llshell to src/arch/i386/llshell (Sometime later I can try it...) - Add the ability to catch exceptions on x86 - Add gdb_stub support to x86 - Removed old cpu options - Added an option so we can detect movnti support - Remove some duplicate definitions from pci_ids.h - Remove the 64bit resource code in amdk8/northbridge.c in preparation for making it generic - Minor romcc bug fixes git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1727 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2004-10-21- Bump the LinuxBIOS major versionEric Biederman
- Rename chip_config chip_operations throughout the tree - Fix Config.lb on most of the Opteron Ports - Fix the amd 8000 chipset support for setting the subsystem vendor and device ids - Add detection of devices that are on the motherboard (i.e. In Config.lb) - Baby step in getting the resource limit handling correct, Ignore fixed resources - Only call enable_childrens_resources on devices we know will have children For some busses like i2c it is non-sense and we don't want it. - Set the resource limits for pnp devices resources. - Improve the resource size detection for pnp devices. - Added a configuration register to amd8111_ide.c so we can enable/disable individual ide channels - Added a header file to hold the prototype of isa_dma_init - Fixed most of the superio chips so the should work now, the via superio pci device is the exception. - The code compiles and runs so it is time for me to go to bed. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1698 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
